Patented Feb. 3, 1931 UNITED STATES PATENT OFFICE NORMAN W. HALSEY, OIYORK, N. Y., ASSIGINOR, BY MESNE ASSIGNMENTS TO PITTSBURGH CLEANSERLABORATORY, INC., A CORPORATION OF NEW YORK CLEANING-MATERIAL FEEDERApplication filed June 25,

The present invention relates to cleaning material feeders for washingmachines and particularly for the usual types of dish-washing machines.More particularly the invention relates to the type offeeder'illustrated and described in my U. S. Patent No. 1,640,319, datedAugust 23, 1927, and its object is to improve the operation and simplifyand cheapen the construction of the feeder.

The invention will 'be described in detail in connection with theaccompanying drawings, in which:

Figure 1 is a cross-section of a typical dish- 15 washlng machineshowing my improved feeder in operative position;

Figure 2 is a central vertical section through the feeder;

Figure 3 is a plan view of the same partly 2o biokendaway to exposethebottom plate there- Figure 4 is a bottom plan of the removable covershowing the inlet valve.

Referring to the drawing, indicates the 25 outer casing of adish-washing machine, 11 a water tank compartment thereof, 12 the dishrack, 13 revolving spray arms which shower the water upon the dishes inthe rack, 14 revolving spray arms which spray the dishes from below, and15 nozzles for spraying rinse water upon the dishes. The water is keptat a substantially constant level in the tank 11 by means of an overflowpipe 16, and it is constantly circulated through the vertical pipe 17and the spray arms 13, 14 by means of a suitable pump 1 My improveddevice for supplying cleaning material to the wash water is indicated atA resting upon a suitable support 19 within the range of the shower ofwater from the spray nozzles 13, 14. Referrin to Figures 2, 3 and 4, mydevice consists o a receptacle having a cylindrical side wall'20, abottom 21, and a top 22 having an upturned neck 23 adapted to receive aflanged cover 24 fitting over the outside of the neck. The cover has aseries of perforations 25 to admit water falling from the spray nozzles,which perfo rations may be closed more'or less as desired. 50 by meansof a valve plate 26 having similar 1929. Serial No. 373,660.

perforations and ada ted to be rotated upon a central pivot 27.gufiicient water i: permitted to enter the perforations 25 to slowlydissolve the soluble cleaning material contained within the receptacle,and the dissolved material escapes throu h perforations 28 in a raisedportion ofthe ottom 21, falling into the wash water in the tank 11.

.When starting the dish-washin machine, with fresh clean water, itis'desira 1e to provide quickly a supply of a cleansing fluid sufficientto charge the water to the requisite strength for cleaning. For thispurpose I provided in the device described in the above mentioned patentcertain internal compartments to which the water had free access and inwhich the cleansing material was quickly dissolved. By means of thepresent invention, these internal compartments are dispensed with, and acheaper construction substituted which has the additional advantage ofbeing easier to charge and more rapid 1n its operation.

Referring to Fi ure 2, 29 indicates an upwardly extending flange which,as illustrated, is an upper extension of the side wall 20. This flangehas perforations 30 for discharge of the dissolved cleaning material,and in conjunction with'the top 22 and neck 23, it constitutes areceptacle 31' to hold a sufiicient amount of cleaning material toprimarily charge the wash water to the proper strength for cleansing. Itwill be apparent that the receptacle 31 is exposed to the shower, andimmediately the apparatus is started the material in the receptacle 31begins to dissolve and to be discharged through the openings 30.

lid 24 is then placed on the neck 23, and thedevice is placed in thewashing machine as illustrated at A in Figure 1. The operation will beunderstood from the foregoing description.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent is: a

1. A cleaning material feeder for washing machines adapted to operatewithin a stream or shower of water, comprisin a closed receptacle forcleanin material aving lapper and lower openings r inlet of water anischarge of cleaning fluid respectively, and an open top receptacle forcleaning material a apted to receive a charge of cleaning material toprovide rapidly a preliminary supply of cleaning fluid, said latterreceptacle comprising a perforated wall surrounding and extending upwardfrom the top of the closed receptacle.

2. A cleaning material feeder for washing machines adapted to operatewithin a stream or shower of water, comprisin a closed receptacle-forcleaning material aving upper and lower openings for inlet of water anddischarge of cleaning fluid res ectively, said receptacle having anupwar ly extending neck and a cover fitting said neck, and an open topreceptacle for cleaning material comprising a perforated wall extendingup- Ward from the side of said closed receptacle and surrounding andspaced from saidneck, substantially as described.

In testimony whereof I hereunto aflix my.
